Answer 1

\(\frac{2x-1}{3}=\frac{x+2}{5}-1\)

\(\Rightarrow\frac{2x-1}{3}=\frac{x-3}{5}\)

\(\Rightarrow\left(2x-1\right).5=3.\left(x-3\right)\)

\(\Rightarrow10x-5=3x-9\)

\(\Rightarrow10x-3x=-9+5\Rightarrow7x=-4\Rightarrow x=-\frac{4}{7}\)

Answer 2

Phạm văn hùng mk chép sai đề rồi bạn làm lại nhé

\(\frac{2x-1}{3}=\frac{x+2}{5}+1\)

Answer 3

\(\frac{2x-1}{3}=\frac{x+2}{5}+1\)

\(\Rightarrow\frac{2x-1}{3}=\frac{x+7}{5}\)

\(\Rightarrow\left(2x-1\right).5=3.\left(x+7\right)\)

\(\Rightarrow10x-5=3x+21\)

\(\Rightarrow10x-3x=21+5\)

\(\Rightarrow7x=26\Rightarrow x=\frac{26}{7}\)
